Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] A method for realizing low friction of tapered roller bearings. First, the angle between the large retaining ring of the tapered roller bearing and the generatrix of the raceway is greater than 90 degrees; The contact between the roller spherical surface and the large retaining ring is changed from intersecting two-point contact to smooth one-point contact, thereby reducing the number of contact points, improving the contact condition between the two, reducing the friction between the large retaining ring and the spherical surface, and making the tapered roller rotate ability has been effectively improved. In addition, through the comprehensive application of the design principles of ball bearings, the anti-skew ability of the ribs to the tapered rollers is enhanced, and the high-speed and heavy-duty of the tapered roller bearings are realized. ...

Abstract

The invention discloses a method and a structure of a taper roller bearing low friction. The invention causes the angle between a large retaining ring of the taper roller bearing and a raceway generatrix more than 90 DEG and reduces the ball diameter of the sphere at one end of the taper roller, meanwhile, the invention implements the object that the contact between the taper roller sphere and the large retaining ring is changed from crossed multi-point contact into slippery one-point contact; meanwhile, the invention presents the angle range is 90 DEG-93 DEG; furthermore, the ball diameter complies with the specific requirement of 40%-80% of the stipulated value of the existing drawing of the products. The invention is beneficial for reducing the friction, reducing the abrasion between the large retaining ring and the sphere and implementing the high-speed heavy loading of the taper roller bearing.

Description

technical field [0001] The invention relates to a method for reducing friction, in particular to a method for realizing low friction of tapered roller bearings and its structure. Background technique [0002] As we all know, bearings are a conventional standard part, and tapered roller bearings are widely used because they can bear both axial and radial thrusts and are small in size. However, due to the limitation of its structure and manufacturing precision for a long time, it is generally used in medium and low speed heavy-duty industries. However, with the continuous breakthrough of its related technologies recently, its manufacturing precision and speed have been greatly improved. Its smaller The volume and excellent performance are attracting the attention of the automobile manufacturing industry, so the development of low-noise, high-speed tapered roller bearings has been a difficult problem that the bearing industry has been working hard to overcome for a long time. ...
